To find the probability that the spinner lands on a vowel, we first need to identify how many vowel spaces are present among the 26 labeled spaces (A to Z). The vowels are A, E, I, O, and U.
Counting the vowels:
- A
- E
- I
- O
- U
This gives us a total of 5 vowels.
Now, we determine the total number of spaces on the spinner, which is 26.
The probability \( P \) of landing on a vowel can be calculated using the formula:
\[ P(\text{vowel}) = \frac{\text{Number of favorable outcomes}}{\text{Total number of outcomes}} = \frac{5}{26} \]
So, the probability that the spinner lands on a vowel is:
\[ \frac{5}{26} \]
